3_OPERATING INSTRUCTIONS

PLACEMENT AND TESTING

To start the power tool, push the On/Off switch 3
forwards.
To lock the On/Off switch 3, press the On/Off switch 3
down at the front until it latches.
To switch off the power tool, release the On/Off switch
3 or, if it is locked, briefly push down the back of the
On/Of switch 3 and then release it.
Check grinding tools before using. The grinding
tool must be mounted properly and be able to
move freely. Carry out a test run for at least one
minute with no load. Do not use damaged, out-of-
centre or vibrating grinding tools. Damaged grin-
ding tools can burst and cause injuries.

TOOL CHANGE

Before any work on the machine itself, pull the
mains plug.
Grinding and cutting discs become very hot while
working; do not touch until they have cooled.
- Clean the grinder spindle 5 and all parts to be
mounted.
- For clamping and loosening the grinding tools, lock
the grinder spindle with the spindle lock button 2.
Actuate the spindle lock button only when the
grinder spindle is at a standstill.
Otherwise, the machine may become damaged.
Grinding Disc
Pay attention to the dimensions of the grinding tools.
The mounting hole diameter must fit the mounting
flange without play 7. Do not use reducers or adapters.
When using diamond cutting discs, pay attention that
the direction-of-rotation arrow on the diamond cutting
disc and the direction of rotation of the machine (see
direction-ofrotation arrow on the machine head) agree.
See graphics page for the mounting sequence.
To fasten the grinding/cutting disc 8, screw on the
clamping nut 9 and tighten with the twohole spanner.
After mounting the grinding tool and before swit-
ching on, check that the grinding tool is correctly
mounted and that it can turn freely. Make sure that
the grinding tool does not graze against the pro-
tection guard or other parts.
Dust/Chip Extraction
Dusts from materials such as lead-containing coatings,
some wood types, minerals and metal can be harmful
to one's health. Touching or breathing-in the dusts
can cause allergic reactions and/or lead to respiratory
infections of the user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in connection
with woodtreatment
preservative). Materials containing asbestos may only
be worked by specialists.
– Use dust extraction whenever possible.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filterclass respirator.
Observe the relevant regulations in your country
for the materials to be worked.
